Investigating the role of attitudes in the choice of an electric scooter via a hybrid choice model : an exploratory application to the city of Trieste, Italy
No full textThe paper illustrates a stated preference study focused on the Italian market aimed at understanding the main factors affecting the scooter choice, with a specific interest at comparing electric and conventional ones. A hybrid choice-modelling framework is used to capture not only the traditional scooter attributes and socio-economic variables but also to test whether attitudinal factors play a role. Both technological (range, power, speed) and economic (price, fuel costs, circulation tax, insurance premium) attributes proved relevant, and ceteris paribus respondents value e-scooters less than conventional ones. All the identified latent variables play a role, the most significant one being interest for scooter performance, followed by concern for the environment and scooter knowledge
The characteristics of the demand for electric scooters in Italy: An exploratory study
No full textThe paper illustrates a stated choice experiment aimed at understanding the main factors influencing the choice between electric and petrol scooters in Italy. A discrete choice modelling framework is used to assess the role played by the scooter's technical and financial attributes, and the respondents' socio-demographic variables. We performed a stated choice experiment with 518 respondents living in various Italian cities including Rome and Milan, where an electric scooter sharing service is active. We find that purchase price, fuel economy, annual cost of circulation tax and insurance premium, driving range, engine power, manufacturer's country and removable battery are consistently statistically significant across the different specifications. The electric scooter, however, is still characterized by a negative alternative specific constant, signaling a ceteris paribus negative perception relative to the conventional one. Although the national and local governments have undertaken actions to support electric scooters' uptake, the current consumers' preferences indicate that in Italy several non-monetary factors and a still inadequate supply limit the chances that electric scooters will extend significantly their market share
Dissecting the total cost of ownership of fully electric cars in Italy: The impact of annual distance travelled, home charging and urban driving
Full text linkThe paper quantifies the importance for cost competitiveness of fully electric cars (BEVs) of three determinants of the total cost of ownership (TCO): the annual distance travelled (ADT), the percentage of urban trips, and the availability of a private parking space. The estimates are performed with reference to the Italian car market. We find that charging at home increases the break-even BEV manufacturer's suggested retail price (MSRP) relative to other propulsion systems by €2866-11,466, depending on the ADT. Driving in urban areas increases the break-even BEV MSRP by €910-10,314, depending on the ADT and on the referenced propulsion system. Taking into account the share of Italian drivers who own a garage and drive in urban areas, we find the cheapest BEVs are cost competitive without a subsidy with respect to the HEVs for 11.8% of the Italian drivers, but not with respect to the diesel and petrol cars, unless extremely high annual distances are driven. With the purchase subsidy recently introduced by the Italian government, the cheapest BEVs become competitive also with respect to the diesel cars, but not relative to the petrol cars, unless more than 12,500 km are annually driven
Mandating the use of the electric taxis: The case of Florence
Full text linkThis paper discusses a policy enacted in 2016 by the city of Florence mandating the use of electric vehicles for the taxi service. We interviewed the taxi license owners (carriers), their co-operatives and the city administrators to evaluate the policy implementation, its acceptability and the cost-competitiveness of electric taxis (e-taxis) with respect to their hybrid and diesel alternatives. Using the data collected during the interviews, we estimated the total cost of ownership (TCO) of e-taxis and their conventional counterparts for the models comprising the Florence taxi fleet. We find that e-taxis already represent a valid alternative to the conventional ones not only from an environmental point of view but also from a private economic one. In particular, when the Florence-specific discounted purchase prices are considered and the base case scenario applies, e-taxis are the cheapest choice in terms of TCO and no financial incentives are needed. When the manufacturer suggested retail prices are considered, e-taxis are slightly less cost-competitive than hybrid taxis but more cost-competitive than the diesel ones. Sensitivity analyses are performed to evaluate the impact of the annual distance travelled, Ecobonus purchase subsidy, net revenue loss, annual percentage rate charged to finance the taxi acquisition and insurance premium
Youngers’ Preferences for Electric Cars in Italy and China: a stated choice analysis
No full textcenter dot This paper compares drivers' car preferences in Italy and China to discover differences and commonalities in the car choice determinants. We per- formed a stated-choice experiment and collected data from a sample of Italian (N = 436) and Chinese (N = 358) young respondents by carrying out a web based questionnaire administered from March to November 2021. We estimated a mixed logit (MXL) model to investigate the roles of purchase price, driving range, and socio-economic variables in the choice of electric vehicles (EVs). We found that financial and non-financial attributes played a relevant role in both countries. Italians had a stronger sensitivity about the EV range than the Chi- nese respondents. The availability of garage charging points positively affected the choice of BEVs for Italians, while no significant result was found in China. We then used the estimated model to evaluate the impact of policy variable changes on the selection of BEVs. We found that incentivizing policies that si- multaneously target the price and driving range could stimulate EVs' uptake more than a single policy
Insights into peer-to-peer carsharing: Modelling and scenario analysis via a Bass diffusion agent-based model
Full text linkOur paper aims at estimating the uptake of peer-to-peer carsharing (P2PCS) in less-densely populated areas and how it could be influenced by innovation, social interaction and transport policies. We specified a Bass Diffusion agent-based model including two modules representing the supply and demand of P2PCS. Both modules are parametrized with data derived from a discrete choice survey of potential users (N = 449) representative of the population living in Friuli-Venezia Giulia, an Italian region bordering with Austria and Slovenia. We specified the rental rate as a dynamic variable that varies according to the excess of demand or supply. Innovation and imitation effects change the status of car owners and car drivers into potential P2PCS users. According to our simulations the P2PCS market would reach a steady state at a rental rate of 6.1 euro/h with 7% of car owners and car renters engaging in the system. We also found that if the preferences for the servitization paradigm were more diffused, P2PCS would be used by 11% of the population at a rental rate of 5.5 is an element of/h, and that adopting a package of highly effective policies supporting both the demand and the supply would increase the market share up to 42%
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
